  If your Daikin Air Conditioner isn't cooling or heating well, first ensure that nothing is blocking the air inlets or outlets of either the indoor or outdoor unit. Clear any obstructions to improve ventilation. Also, make sure the air filter is clean; if it's clogged, have a qualified service person clean it. Check that the set temperature, fan speed, and airflow direction are appropriate for your needs. Ensure doors and windows are closed to prevent drafts, and use curtains or blinds to block direct sunlight. Consider if there are too many people in the room or excessive heat sources, as these can affect cooling performance.

  If your Daikin Air Conditioner isn't working at all, start by checking if a fuse has blown. Next, inspect the power circuit breaker. If it's in the OFF position, switch it on. However, if the breaker has tripped (trip position), do not attempt to reset it; instead, contact your local dealer for assistance. Finally, check for a power failure in your area and wait for the power to be restored. Note that if a power failure occurs during operation, the air conditioner will automatically restart once the power is back on.

  To address this issue with your Daikin Air Conditioner, first, verify that the ON/OFF timer operation is not active. If it is, turn it off. Also, check if a remote control device is connected and, if so, contact the central control room that initiated the stop. Similarly, if the display for centralized control is lit, contact the central control room responsible for the stop command.
